HOSPITAL BED.

Application filed July 25, 1924. Serial No. 728,213.

This invention relates to a bed mainly designed for hospital use, thegeneral object of the invention being to provide means whereby the bedcan be rotated about a vertical axis and to hold it in adjustedposition.

Another object of the invention is to provide means for changing theinclination of the bed as desired.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is an elevation of the invention.

Figure 2 is a plan'view.

Figure 3 is a sectional of Figure 2.

Figure 4 is a section on line 4+4: of Figure 3. j

Figure 5 is a detail view of one of the locking parts.

In these views, 1 indicates a supporting plate or disc to which the fourcurved legs 2 are connected so that this plate is supported inhorizontal position above the floor. A second plate or disc 3 isrotatably mounted on the first plate by means of the ball bearings atand the stud 5 depending from the center of the plate?) through a holein the plate 1, a nut 6 on the screw threaded end of the stud holdingthe parts in assembled position. ward from the top of the plate 3 andcarries a pivot bolt 8 for the bed A, the bolt extending throughthe'angle irons 9 which are arranged at the center of the bed frame andare connected withthe end pieces thereof. The projection 7 extendsbetween the two view on line 3-3 angle irons 9 as shown in Figure 4.Thusthe bed frame can be rocked about the pivot 8, as shown in dottedlines in Figure 1, and it is held in adjusted position by means of a rod10 passing between the bars 9 and having a wedge latch member 11fastened to itsinner end for engaging any one of a plural ity of notches12 formed in the projection7. The other end of the rod passes throughlahole in'the end piece of the bed and is bent tion without disturbinghim.

A flat'projection 7 extends upto form a handle 13 so that the rod can bepulled outwardly against the action of the spring 14 which tends to holdthe membe 11 in engagement with the notch 12. a I also provide means forholding the plate 3 and the bed against rotary movement, such meanscomprising a bent rod 15 which passes through a hole formed in a sidebar, of the bed and through a hole formedin a bracket 16 placed on theplate 3 and which has its inner end adapted to engage any one of anumber of holes 17 formed in the edge of the plate 1. The other end ofthe rod is also bent to provide a handle 18 and a spring 19 tends tohold the rod in engagement with one of the holes 17.

From the foregoing it will be seen that I have provided a bed Which maybe tilted to various positions or held in a horizontal position androtated about a vertical axis. The bed is of simple but substantialconstruction and may be manufactured to sell at lowcost. It is very easyto keep clean so that it is sanitary and especially fitted for hospitaluse.

By having the bed rotatable about a vertical axis and tiltable about ahorizontal axis the bed can be adjusted to place the patient in the mostcomfortable position and situa- It is thought from the foregoingdescription thatthe advantages and novel features of my invention willbe readily apparent.

I desire it to be understood that I may make changes in the constructionand in the. combination and arrangement of the several o parts, providedthat such changes fall within thescope of the appended claim.

VVhat- I claim is A bed comprising a supporting plate,'-legs connectedwith the same, a second plate mounted on the first plate, anti-frictionmeans between the two plates, a centrally arranged stud on the secondplate passing through the ccnter of the first plate, a nut threaded onthe bottom of the stud, an upwardly extending projection on the secondplate having fiat sides with notches formed in one edge thereof, a bedframe pivotally connected with the projection so that it can be movedabout a horizontal axis, said frame including a pair of parallel stripsat the center thereof between which "the projection passes, with thepivot pin passing through the strips and the projection, a springpressed locking bar carried by the bed frame and having a part adaptedto engage any one of the notches in the projection for holding the bedframe in adjusted position, a sec-- ond spring pressed locking bar onthe frame, the first plate having holes therein adapted to receive theinner end. of said last men engaging one of the holes in the firstplat-e.

In testimony whereof I my signature,
